Applies to:

Oracle Database Appliance Software - Version 12.1.2.6 to 12.1.2.6 [Release 12.1]
Big Data Appliance X5-2 Hardware - Version All Versions to All Versions [Release All Releases]
Oracle VM - Version 3.2.2 to 3.2.3 [Release OVM32]

Information in this document applies to any platform.

Symptoms

ODA OAK 12.1.2.6.

Unable to mount a CFIS windows share automatically, manual mount works fine:

[root@oda01]# mount -t cifs -o credentials=/etc/.cifs_credentials,uid=oracle,gid=oinstall //ps01/MyOraArchive /mnt/MyOraArchive

After successfully mounting a CFIS Windows share manually, the attempt to do so automatically fails:

[root@oda01 etc]# umount /mnt/MyOraArchive/

Added an entry in the fstab file

[root@oda01 etc]# cat /etc/fstab
LABEL=rootfs / ext3 defaults 1 1
LABEL=bootfs /boot ext3 defaults 1 2
LABEL=u01fs /u01 ext3 defaults 0 0
LABEL=swapfs swap swap defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
xenfs /proc/xen xenfs defaults 0 0
//ps01/MyOraArchive /mnt/MyOraArchve cifs credentials=/etc/.cifs_credentials,uid=oracle,gid=oinstall 0 0

Issued mount -a command ...

[root@oda01]# mount -a
Couldn't chdir to /mnt/MyOraArchve: No such file or directory

Changes

Cause

missing mount option "_netdev"

Solution

Add "_netdev" to /etc/fstab:

\\ps01\MyOraArchive /mnt/MyOraArchive cifs credentials=/etc/.cifs_credentials,uid=oracle,gid=oinstall,_netdev 0 0
